To aZZ whom it may concern..- 1 of two setting'tools which we use to adjust Be it known that we, GEORGE ASHWORTH I the fiatbar in. position.

The remainder of the parts 15 the flats by means of lead rivets,which neeeswhich appear in Fig. 1 are substantially of sitated the bar being much wider than the an ordinary character so far as card-setting carding-surface; but in the year 1877 we inmachinery is concerned, and we therefore do vented and introduced into use in Great Britnot claim them as new. ain a method of attaching the clothing to l Preparatory to thefixing ofa flat-bar in 2o nicked metal bars by means of metal staples, position two setting-tools are slid into the which required much narrower margins on seatings (Z d. In Figs. 7 and 8 it will be seen the card-clothing, so that we were enabled to I that the standard 6, which carries the setting increase the number of flats in the endless fingers f, is formed with Vs e, which are chain, and to so increase the useful effect of planed and fitted to slide in the seating d, so 2 5 the carding-engine. For this invention we I that the tool can be placed at once in the corobtained Letters Patent of the United Kingrect position. The standard is pushed fordom, No. 4:,091, of the year 1877. The object 1 ward in the seating until an adjustable screw, of our present inyention is to secure the clothj 6 comes in contact with the side of the bed ing to such nicked bars by means of a modi- I of the machine.

The tool is prowhich forms staples froinacontinuous length vided with two thin fingers, j', which are of wire and passes them through the fonndai adapted to enter two contiguous nicks in the tion-fabric of the card-clothing and the nicks fia-tbar. In Fig. '7 a part, b, of the flat-bar in thebar and clamps the points of the staples is shown .in position. The nicks in the bar c 5 at the back of the bar. The machine is proare shown at I).

Each end of the barb enters between a plan yiewshowingthe jaws holding a length a movable gripping-dog, o, and a fixed part of wire.

The two settingback of the bar. Fig. 7 is an elevation of one tools are now withdrawn from the seatings d.

This setting and fixing of the bar can be done in a few seconds. \Vire is fed to the machine and pas. into the jaws (t when they are open. One of the said jaws, a, is fixed, the other jaw, a, being hinged, as clearly shown in Fig. 2. The hinged jaw is provided with a hooked tail, which is operated upon to open and close the jaws by the rod or part which operates the crown in the ordinary set-ting-machine, such rod being indicated by the letter a inI ig. would come in contact with the card-teeth on the flat, we have been obliged to dispense with it, and have adopted the holding-jaws a a in lieu of the ordinary tongue and crown. hen the wire has been fed forward by the ordinary means, (not shown in the drawings.) the rod (/5 is pushed down. onto the tail (1*, thereby forcibly closing the jaw (1 against the jaw a. It will be seen that the outer tip of the jaw ct extends a little beyond the end of the jaw a, and is also bent a little, so as to extend a little beyond or in front of the grooved end of the jaw a. The wire is gripped between the ends of the jaws. The wire being thus held is cut by the cutters, which act in the ordinarymanner, with the exception that we shape the cutters to remove a piece of wire, so as to form sharp points upon the ends of the wire. The length of wire then bent into ast-aple by the advance of the ordinary side wings, a, as seen in Fig. 5. The bar which carries the jaws (L is then pushed forward, as in the ordinary machine, and the staple is driven through the foundation of the eard-clothing and through two nicks in the bar. Before the staple is driven fully home the rod (1 is raised by the same movement which in the ordinary machine withdraws the crown out of .the way, and by such movement the jaw a is lowered so that it clears the lower edge of the flat-bar. The importance of the exact adjustment of the flat-bar will be apparent, because if the bar were not exactly in the correct position horizontally the points of the staple would strike the metal, and it the vertical posit ion were not correct the staple would either strike the bottoms of the nicks or otherwise there would be liberty for the clothing to become relaxed from the degree to which it had been stretched. The points of the wire staples, which project from the back of the bar, pass close to two uliiright fingers, which are formed on the end of an adjustableplate, g, which is secured to a sliding plate, 7!,which is fitted to slide on the top of the fixed bracket As the ordinary crown i. A spring, 7;, presses the plate 71 toward the flat-bar, an adjustable screw, 7t, limitin this movement.

A plan view of th e end of the pl ate g is shown in Figs. ll and 12, in which the flat bar and staple. also appear. In Fig. 12 the st-a1 )1e is in the position as when just driven home. The carriage Z, on which all the staple forming and fixing parts are mounted, as is usual, is now moved along the bed by the rotation of the ordinary screw, 97/, the movement of the carriage being equal to the distance from the center of one nick to the center of: the next; but one. The bracket 1 is attached to a projection, Z, on the carriage, so that the plate g moves with the carriage, and the fingers g bend back the ends of the staple by the yielding pressure of the spring in the manner shown in Fig. it.

Having descrilmd our invention, we hereby declare that what we claim i s 1. In a machine for wiring card-clothing to flat-bars, the setting-tool cf, provided with a finger or fingers to enter nicks in the flat bar, in combination with. the seating in the frame, into which the said tool slides, substantially as set forth.

2. The setting-tools provided with lingers to enter into nicks in the flat-bars, in combination with the dog apparatus to receive and hold the flat-bar, substantially as set forth.

The setting-tools cf, the seatings for such setting-tools, the bar-holders, the wire-grip ping jaws, and the clamping-tool to bend up the wire points, in combination with the sliding carriage provided with ordinary n1echanism for cutting lengths of wire, bending such wire into staples, and .l'orcing such staples through the card-clothingfoundation and the. nicks in the flat-bar, substantially set forth.

4. The carriage provided with ordinary mechanism for cutting lengths of wire, bending such wire into staples, and forcing such staples through the card-clothin g foundation and the nicks in the flattbar, in combination with a elanipingtool, g g, connected to the carriage to bend up and clamp the wire points, all substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
